so today has been fun. Switched cog from old to new wheel, switched 4 tires, adjusted stem height, swapped 2 cranks, 3 pedal sets, changed 3 chainrings, 2 brakes and a new set of bars, and only 1 bike is presently ridable. Still to go new race face crank on the mtb (thanks agin Krusty!!), tires on wifes bike, old cog back on old wheel, fix brake and make some coffee asap.
